Talk given 8/4/22 at the 20th International Radiance Workshop, Toronto, Canada

This presentation, given in collaboration with Alan DeMarche at Loisos + Ubbelohde, covered the long and complex process which I, Alan, and our colleagues went through to develop a highly accurate simulation model of a fencing material that is being used as a shading material in a very large building in the Middle East. To effectively simulate this material, we had to generate a Bidirectional Scattering and Distribution Function (BSDF), which we then validated in a number of ways against samples of the actual material.
